c)
hepatocyte is a stable cell.the stable cells divide [usually] only infrequently but can be stimulated to divide when cells are lost

the rest are labile cells and are continuously dividing.proliferate continuously through post-natal life and have a very high regenerative capacity. These can be very susceptible to toxic agents such as anti-cancer chemotherapy drugs and radiation.

Permanent cells normally only divide in embryonic and fetal life (or maybe in the early post natal period). Cells in this category cannot be replaced when lost and they have only a very limited (if any) capacity to divide. This group includes cardiac muscle cells, photoreceptors in the retina and neurones.
